Consumer<T>函数式编程总结

public class Parent {

    public void getName(String name){
        System.out.println("name:" + name);
    }

}

public class Son extends Parent{

    @Override
    public void getName(String name) {
        System.out.println("hello -->" + name);
    }
}

public class Handler {

    public void handle(Consumer<String> consumer, String name){
        consumer.accept(name);
    }

}

public class Test {

    public static void main(String[] args) {
        Parent parent = new Son();

        Consumer<String> consumer = parent::getName;

        Handler handler = new Handler();
        handler.handle(consumer, "guodong");
    }


}

总结：提供一个T类型的输入参数，不返回执行结果，也是可以用来接耦。
